A simple GCD display.
Inspired by zork's ring works, I decided to write myself a ring lib to mess around with, and eventually came up with the GCD display.
Console command "/gcdring" to toggle the config mode.
If no watched spell is specified, default spell (per class) is used.
smooth GCDRing while burst of cooldowns, especially class whose GCD is affected by haste. (and class who spam lots of cast events, e.g. hunter)
The position is saved by layout cache.
We all know that sometimes GCD is jumpy.. just blame blizzard
